- A carbonate is a CO32 ion formed when carbon
- dioxide dissolves in water; any salt formed
- by this ion and another chemical element,
- usuallyis a metal. Carbon dioxide (CO2)
- dissolves sparingly in water, for e.g. when
- rain falls through the air. Calcium carbonate
- (CaCO3) (chalk, limestone, and marble) is one
- of the most abundant carbonates known, being
- a constituent of mollusc shells and the hard
- outer skeletons of crustaceans.
